Trying to heal as holy priest at Un'Sok is just mind-boggling, since basically evey smart heal you use is somehow going to heal the debuffed player. So I've been trying to approach it with a new strategy including using Halo instead of Cascade, but the problem is that I am very bad at estimating the range of Halo and now I wonder: is there any add-on that can show a circle around your character with a fixed radius of 30y?
